CAUTION

䡬 The selection examples shown in Table 5 should

be considered as general standard. As different

types of tightening screws and different materials

to be tightened are used in actual works proper

adjustments are naturally necessary.

䡬 When using the impact driver drill with a machine

screw at HIGH (high speed), a screw may damage

or a bit may loose due to the tightening torque is

too strong. Use the impact driver drill at LOW (low

speed) when using a machine screw.

NOTE

The use of the battery BCL1415 and BCL1815 in a

5cold condition (below 0 degree Centigrade) can

sometimes result in the weakened tightening torque

and reduced amount of work. This, however, is

a temporary phenomenon, and returns to normal

when the battery warms up.

7. Mounting and dismounting of the bit

(1) After inserting a driver bit, etc. into the keyless drill

chuck, firmly grasp the ring and tighten the sleeve

by turning it toward the right (in the clockwise

direction as viewed from the front) (See Fig. 8).

䡬 If the sleeve becomes loose during operation, tighten

it further. The tightening force becomes stronger

when the sleeve is tightened additionally.

(2) Dismounting the bit

Firmly grasp the ring and loosen the sleeve by

turning it toward the left (in the counter-clockwise

direction as viewed from the front) (See Fig. 8).

CAUTION

䡬 When it is no longer possible to loosen the sleeve,

use a vise or similar instrument to secure the bit. Set

the clutch mode between 1 and 11 and then turn the

sleeve to the loose side (left side) while operating the

clutch. It should be easy now to loosen the sleeve.

8. Confirm that the battery is mounted correctly

9. Check the rotational direction

The bit rotates clockwise (viewed from the rear

side) by pushing the R-side of the selector button.

The L-side of the selector button is pushed to turn

the bit counterclockwise (See Fig. 9)(The

and

marks are provided on the body).

CAUTION

䡬 Always use this unit with clockwise rotation, when

using it as an impact drill.

10. Switch operation

䡬 When the trigger switch is depressed, the tool

rotates. When the trigger is released, the tool stops.

䡬 The rotational speed of the drill can be controlled by

varying the amount that the trigger switch is pulled.

Speed is low when the trigger switch is pulled slightly

and increases as the trigger switch is pulled more.

NOTE

䡬 A buzzing noise is produced when the motor is about

to rotate. This is only a noise, not a machine failure.

11. For drilling into brick

Excessive pressing force never increases drilling

speed. It will not only damage the drill tip or reduce

working efficiency, but could also shorten the service

life of drill bit. Operate the impact driver drill within

10-15 kg pressing force while drilling into brick.

12. Using the bit holder

CAUTION

䡬 Stow the bit in the specified location on the tool.

If the tool is used with the bit stowed improperly,

the bit may fall and cause bodily injury.

䡬 Do not stow bits that are of a different length,

gauge or dimension than the plus driver bit (65 mm

long) included in the STANDARD ACCESSORIES.

The bit may fall and cause bodily injury.

(1) Removing the bit

Securely hold the main unit and pull out the bit

by holding the tip with your thumb (Fig. 10).

(2) Installing the Bit

Install the bit with steps opposite of when removing.

Insert the bit so that the right and left sides are

equal, as shown in Fig. 11.

MAINTENANCE AND INSPECTION

1. Inspecting the tool

Since use of as dull tool will degrade efficiency and

cause possible motor malfunction, sharpen or

replace the tool as soon as abrasion is noted.
